I haven't skied the Gotama but the new ones ski pretty well, unfortunately have super-weak construction. One friend ripped a binding out of one (Volkl refused to warranty), another friend demolished the bases numerous times hitting things that most skis would have a small scratch from.
Specific ski suggestions are best made knowing height/weight/skiing style/location, but a lot of people are really happy with the K2 Hardside. I'm almost certainly going to get a pair, but waiting for demo days to see which (181 or 188).
As far as backcountry setups, I'd be more than happy to get in to that discussion, but it comes down to one binding: Dynafit. The new Marker F10/12 bindings look ok, but a little weak for anything other than 100% soft snow (not groomers, not bumps, not hucks to hardpack). I love talking skis and backcountry rigs can vary so much depending on use that I don't want to talk specifics.
